The driver is already present in the system at this stage and should be available in the list as ‘Android ADB Interface’

After Updating Driver, please follow below to enter into ADB mode on Host PC and check Neon-RB5 detected as fastboot device

Your target device should have been listed in your command prompt terminal. If not, please check and update the driver in the device manager on your development host.

Enter into Fastboot mode

#fastboot flash abl_a abl.elf
#fastboot flash abl_b abl.elf
#fastboot flash system qti-ubuntu-robotics-image-qrb5165-rb5-sysfs.ext4
